Chelsea[2] boss Jose Mourinho[3] has reportedly told the club's hierarchy that signing a world striker should be their key priority during this summer transfer window and has told his club that Atletio Madrid star Diego Costa[4] is the 'man he wants'.

The club is ready to go all out to sign Costa from Atletico Madrid this summer and have made the striker their top transfer target despite Mourinho's links to Luis Suarez, Gonzalo Higuain, Wayne Rooney and Radamel Falcao .

According to Metro.co.uk, Costa's excellent form in La Liga, scoring 21 goals in 26 matches, has not gone unnoticed and despite Paris Saint-German and Real Madrid linked to the star's service, Chelsea believes that they are in pole position to sign him.

Chelsea are reportedly considered to value Costa at 27 million pounds, which is below is release clause, but a fee that could be accepted if the player pushes for a switch away.

Atletico are already looking for another striker to fill Coasta's gap as the club is well aware of their strikers rising stock and they are certain that offers would arrive for their leading light in the summer, the report added. (ANI[5])
